Sometimes it's tough to choose a particular moment to explore during any particular 'Cougar Town' episode, mainly because each episode is a series of funny moments that are tied together with a little bit of a plot. Most of the plots are pretty straightforward: Andy doesn't like Grayson making fun of him, Bobby doesn't want to introduce his new girlfriend to the gang, Ellie wants to show Jules how much of a control freak she is.
But there aren't many shows who will join all of these plots together using a game of Sardines in a Can. Jules wanted to play it in order to get back a sense of childhood fun. Everyone else used the game to work out their own issues. And Ellie used it to teach Jules a lesson. Oh, and it didn't hurt from a comedy perspective that Jules is awful at the game.
